Katie Power

Few characters debut with the kind of spark Katie Power brought to Marvel's Bronze Age — first appearing in 1984 and quickly becoming one of the most endearing young heroes the House of Ideas has ever produced. A fixture of the Power Pack series, she's spent over four decades sharing adventures with the likes of Julie Power, Jack Power, Alex Power, Lightspeed, and Energizer, making her part of one of Marvel's most charming ensembles. With 115 catalogued appearances — including eight collector-recognized key issues — and a presence stretching from G.I. Joe crossovers to The Transformers, Katie has proven herself a surprisingly versatile corner of the Marvel universe. If you've never explored her corner of comics history, you're in for a genuine treat.
